Axinella labyrinthica   Dendy,  1889 (Sponge)
Organism information awaits expert curation
Class: Demospongiae

Color: Color of the living sponge bright orange; when dry or in spirit yellowish.

Sponge forming sessile, low-growing, erect, branching and anastomosing lamellae. Surface uniformly covered with small, close-set, rather slender conuli, each about 2 millimeter in height. Texture (dry and in spirit) rather hard and fairly tough. Oscula minute, abundantly scattered between the conuli. The single specimen is 71 millimeter in height and 200 millimeter in greatest breadth; the thickness of the lamellae is about 9 millimeter including the conuli.
The skeleton is an exceedingly dense irregular network of spicules, in which it is very difficult to make out any distinct fibres; but stout columns of closely aggregated spicules may be seen running one into each of the surface conuli. The surface of the conuli is densely echinated by projecting spicules springing from these columns. We may imagine the whole skeleton derived from a typical axinellid form by excessive development of the spicules, which are closely united together.
Spicules: (1) Smooth styli, usually more or less bent, especially towards the base, and gradually sharp pointed at the apex; size usually about 0.42 by 0.016 millimeter. (2) Slender curved strongyla, as long as or somewhat longer than the styli, but slenderer.
